| description | The fully heavy axial-vector diquark-antidiquark structures bbc‾c‾ are explored by means of the QCD sum rule method. They are modeled as four-quark mesons T1 and T2 composed of bTCσμνγ5b, c‾γνCc‾T and bTCγμγ5b, c‾Cc‾T diquarks, respectively. The spectroscopic parameters of the tetraquarks T1 and T2 are determined in the context of the QCD two-point sum rule method. Results obtained for masses of these states m1=(12715±86)MeV and m2=(13383±92)MeV are used to fix their strong decay channels. The full width Γ(T1) of the diquark-antidiquark state T1 is estimated by considering the processes T1→Bc−Bc⁎− and T1→Bc⁎−Bc⁎−. The decays to mesons Bc−Bc⁎−, Bc−(2S)Bc⁎− and Bc⁎−Bc⁎− are employed to evaluate Γ(T2). Results obtained for the widths Γ(T1)=(44.3±8.8)MeV and Γ(T2)=(82.5±13.7)MeV of these tetraquarks in conjunction with their masses are useful for future experimental studies of fully heavy resonances. |
